Letters Patent N 95,621, dated October 5, 1869.

The Schedule referred to in these Letters Patent and making-part of the same To all whom it -ma'y concern Be it known that I, AUGUSTUS WEYERMANN, of

Saint Gall, Switzerland, have invented a certain new and useful Method of, and Means for Uniting and Packing the Ends of lipes and Tubes; and I do here? following is a full and exact description thereof, reference being had to the accompaforming a part of this specification. My invention relates to means for coupling or counecting together' the ends vof water, steam, .o r gaspipes, and` is more especially adapted to large pipes or tubes, or such as are not less thanronev'inch in-,diameter.

The object of the said invention is toprovide a cheap, durable, and convenient method of seeming together thev ends of lengths or sections `of pipes, arranged at any desired-angle or inclination toeaeh other, or in a continuous straight line.

Description 'of the Drawings. Figure 1 is a longitudinal secton,illustratig my method of coupling or connecting the ends of pipes, larranged obliquely or atan angle to each other.'

Figure 2 is a similar section, illustrating the application of my invention to pipes, arranged in a straight line with eachother.A

Figure 3.is a ltransverse section, ou the line :t x, figs.1and 2.

Figure 4 is a section of my improved coupling or connecting-pees tonight-angled joints.

Figures 5 and-v6 are sections of such connectingpieces for oblique joints.

Like letters indicate the same parts'tln-onghout the drawing.-

In prabtising my invention, I provide the ends of each pipe, or each length or section of pipe a', with a` movable flange, b, which is kept in place by collars or.

, projections c, on the end, or head a' of each tube. s

The collars c `extend only partially around the tube, and the loose flange b is formed with recesses, or apertures b', which, when brought opposite the collars, as shown in fig. 3, will pass over them, and which may be turned partially around behind the said collars, the ilange being thereby securely held on the pipe.

By this means the ilauges b may be conveniently placed on the end of the pipe, or removed therefrom, and may be adjusted to receive the bolts d, whereby the pipes are secured together.

Between the two pipes or ends to be connected, I place an annular connecting-piece, or coupling, e, which is recessed on each side, to receive afring, f, of India rubber, leather, or other suitable packing-material, against which the end of' each pipe is bedded.

These connecting-pieces are made with their faces either at right angles to the bore of the pipes, as in iig. 4, or with one face, asin fig. 5, or both faces, as in fig. 6, obliqueor inclined at any desired angle to the saine. A

When these connecting-pieces,e` are properly arranged between the ends of the pipes, the loose iianges lb are connected by the bolts and nuts, as shown in figs.

l and 2, and by screwing down the said nuts the two ends ofthe pipe are drawn together, andmade to bed closely on the packing-rings, thereby making the'joint perfectly tight and secure.

In connecting inclined or oblique pipes,tc forin short curves, a short supplementary rlangedpiece, y,

may be placed ing-pieces, e.

The bolts d are passed through the loose flanges b,

between two ofthe annular connectn and through the flange g of this supplementary piece,

as seen in fig. 1.

The head, or end al of each pipe, is preferablymadc somewhat larger in diameter than the intermediate part of the pipe, in order that there may be a. suil'A cient area on the face a?, in contact with the packing-ring f, to insure a tight joint and firm connecllOll. Y

The holt-holes in the flanges b and g' must be made far enough from their centre to' let the bolt-heads Aand nuts he quite clear of the pipes, at whatever angle or inclination to eachv other the -said pipes may be 'In laying the pipes, o1 tubes, the diere'nt sections,- by means of the oblique or inclined connecting-pieces, may be arranged at any desired angle, and by turnlng the said pieces, each part or section may be made to diverge or incline in either a horizontal, vertical, or intermediate direction.

The recesses e', inthe annular connecting-'pieces e, must be so large that the ends of the pipes'maybe adjusted therein to any desired position, without touching the sides of the said recesses. The inner diameter of the said connecting-pieces and of the packing-rings should not be less than the bore of the' pipes.

The flange g', of the intermediate pipe g, is provided with a double series of holes, to receive the bolts from the loose flanges on both sides-of the said intermediate `pipe; or thelatter maybe proiided with a iiauge 'at each end.

A blank flange, or disk, provided with a packingring, may be used for closing the ends ofthe pipes and connections, and the said flange may be secured upon the end of theJ said pipes or connections without the annular connecting-piece.

The outer diameter of the packing-rings f should be equal to that of the recess ein the connectingpiece e.

Leather packing-rings should be used'ibrcold-water pipes, but' for steam-pipes I prefer to make the seid4 1. The pipe a, provided with segmental lips, or anges, in combination with the removable collar 5 and bolts d.
